Description
Technical Field
The invention relates to the technical field of paint, in particular to a water-based paint for color steel tiles.
Background
The color steel tile is also called color pressed tile, is a pressed plate formed by rolling and cold-bending color coated steel plate into various waveforms, has the characteristics of light weight, high strength, convenient and quick construction, shock resistance, fire resistance, rain resistance and the like, and is widely applied to roof and inner and outer wall decoration of industrial and civil buildings, warehouses and large-span steel structures. Because the thermal expansion coefficients of the paint and the color steel tile are different, tiny cracks are easy to generate on the paint surface when the paint is subjected to high temperature and severe cold, and air and water can corrode a steel plate along the cracks, so that the steel plate is corroded. Particularly, in coastal areas, due to the influence of marine climate, rainwater is high in acidity, and when cracks occur in the paint, the rainwater can accelerate the corrosion of the steel plate, so that the paint resistant to acid corrosion is needed.
In order to improve the corrosion resistance of the color steel tile, acid and alkali corrosion resistant epoxy resin such as CN106967347A, CN101343499B is often added into the paint, but due to the high hardness, large brittleness and poor weather resistance of the epoxy resin and the difference in thermal expansion coefficient between the paint and the color steel tile, the adhesion and toughness of the paint are deteriorated, the paint surface will fall off or crack for a long time, and the color steel tile will be corroded by rain, thereby reducing the corrosion resistance of the paint.
